Sila -- Moral Conduct
Sila or moral conduct is the principle of human behaviour that promotes orderly and peaceful existence in a community. Rules of moral conduct are to be found in every religion. They may resemble other codes of conduct to a greater or lesser degree depending on the Teacher or religious system from which they originated. Usually they comprise lists of actions from which to abstain, implying that any actions not covered by the prohibitions are permissible. A good example is afforded by the five Silas (of Buddhism), namely to abstain from taking the life of sentient beings, to abstain from taking possession of anything that has not been given by its owner, to abstain from sexual misconduct, to abstain from lying or evil speech, and to abstain from intoxicating drinks which are a primary cause of negligence.

Lay Morality
The Buddhist perspective of morality is given in a nutshell in the little Pali verse. "Sabba papassa akaranam - kusalassa upasampada sachitta pariyodapanam - etam buddhanu sasanam" "To keep away from all evil, cultivate good, and purify one's mind is the advice of all Buddhas."

The Meaning of Sin and Evil
"Buddhism has a completely satisfying answer to evil and sin. The Buddhist approach would be to question your "desire" to be without sin or evil, to look at the question itself. Why would you limit your life? To trap you into an experience that western language finds difficult to say directly. To direct your search to the real truth. Here our normal "logical" English language just breaks down. What is this "illogical" experience that is not linear and deductive? The answer is "There is - in fact - a life that can be experienced outside of the level of thinking." I call that the essential teaching of Buddhism."

Economics in Buddhism
To live in this world, wealth is very essential. So everyone has to work for money as society depends on economics. But we should not regard wealth to be like a god. Trying to get wealth through right means is not wrong. Competition can be bad if it is directed by ulterior motives. But it is very helpful and effective concerning success and progress where the motive is good and correct. The man who has no selfish attachment to wealth is able to do a lot of things for society with wealth that was either accumulated by his own effort or inherited.
